6.1 Valve spring failure

to be clear. the locator is below the spring. because of what? Sideplay? On top is the retainer.

I just changed the springs. without cages. thought the ls1511 springs were made for the 2-3mm more height required.

so i need:
- shims to compensate the height difference,
- locators because to terminate side play
retainer and locks remain stock.

why new seals?
